Enhance container security with Prevasio's sandbox. Isolate and "detonate" containers in a safe environment to uncover hidden threats and prevent breaches. Prevasio sandbox 'Detonates' containers in a safe virtual environment Network traffic analysis Prevasio Sandbox intercepts and inspects all network traffic generated by containers, including HTTPS traffic. SSL/TLS inspection is enabled with Prevasio’s MITM proxy certificate being dynamically injected into the virtual file system of the analysed container images. Currently, Prevasio Sandbox provides HTTPS interception for the 10 most common Linux distributions. The following example demonstrates an interception of HTTP and HTTPS traffic in a container spawned from a public Docker Hub image. Schedule a Demo Vulnerability scan Prevasio Sandbox scans container images for the presence of any vulnerable packages and libraries. For example, this ️ Docker Hub image contains critical vulnerabilities in 28 packages. Schedule a Demo ML classifier for malware Any x32/x64 ELF executable files created both during container image build phase and the runtime are scanned with Prevasio’s Machine Learing (ML) model. The ML model used by Prevasio relies on ELF file’s static characteristics, its entropy, and the sequence of its disassembled code. Here is an example of a malicious container image hosted️ at Docker Hub, that was picked up by Prevasio’s ML Classifier. Let’s see what happens if we recompile Mirai bot’s source code️ , by using custom domains for C2 (command-and-control) traffic. The Dockerfile with instructions to fetch, modify, and compile Mirai source code is available here️ . As you see in this example, the use of ML provides resistant detection, even if the malware was modified. Schedule a Demo Automated Pen-Test Full static visibility of the container’s internals is not sufficient to tell if a container image in question is safe indeed. During the last stage of its analysis, Prevasio Sandbox simulates attackers’ actions, first trying to fingerprint services running within the analysed container, and then engaging exploits against them. In addition to that, the pen-test performs a brute-force attack against an identified service (such as SSH, FTP or SQL), in order to find weak credentials that would allow the attackers to log in. As the pen-test is performed in an isolated environment, it poses no risk to the production environment. The following example demonstrates how the automated pen-test has identified the type of MySQL server running inside a container spawned from this️ Docker Hub image, then successfully brute-forced it and found working credentials against it. Schedule a Demo System event graph Prevasio collects kernel-level system events within a running container: File system events Network events Process lifecycle events Kernel syscalls User call events These events are then correlated into a hierarchy, visually displayed in the form of a force-directed graph. The graph allows to visually identify problematic containers and also quickly establish remote access points. Here is an example of an event graph generated for ️this Docker Hub image.

Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 4/27/23 Published Ensuring your cloud environment is secure and compliant with industry practices is critical. Cloud security best practices will help you protect your organization’s data and applications. In the process, reduce the risks of security compromise. This post will walk you through the best practices for cloud security. We’ll also share the top cloud security risks and how to mitigate them. The top 5 security risks to cloud computing right now Social engineering. Social engineering attackers use psychological deception to manipulate users into providing sensitive information. These deception tactics may include phishing, pretexting, or baiting. Account compromise. An account compromise occurs when an attacker obtains unauthorized entry to it. A hacker can access your account when you use weak passwords or steal your credentials. They may introduce malware or steal your files once they access your account. Shadow IT. This security risk occurs when your employee uses hardware or software that the IT department does not approve. It may result in compliance problems, data loss, and a higher risk of cyberattacks. Insider activity (unintentional or malicious) . Insider activity occurs when approved users damage your company’s data or network. These users can either do it purposefully or accidentally on-premises. For example, you may disclose private information unintentionally or steal data on purpose. Insecure APIs . APIs make communication easier for cloud services and other software applications. Insecure APIs can allow unauthorized access to sensitive data. This could, in turn, lead to malicious attacks, such as data theft. The attackers could also do illegal data alteration from data centers. 16 best practices for cloud security Establish zero-trust architecture Use role-based access control Monitor suspicious activity Monitor privileged users Encrypt data in motion and at rest Investigate shadow IT applications Protect Endpoints Educate employees about threats Create and enforce a password policy Implement multi-factor authentication Understand the shared responsibility model m Audit IaaS configurations Review SLAs and contracts. Maintaining logs and monitoring Use vulnerability and penetration testing Consider intrusion detection and prevention One of the most critical areas of cloud security is identity and access management. We will also discuss sensitive data protection, social engineering attacks, cloud deployments, and incident response. Best practices for managing access. Access control is an integral part of cloud network security. It restricts who can access cloud services, what they can do with the data, and when. Here are some of the best practices for managing access: Establish zero-trust architecture Zero-trust architecture is a security concept that treats all traffic in or out of your network as untrusted. It considers that every request may be malicious. So you must verify your request, even if it originates from within the network. You can apply zero-trust architecture by dividing the system into smaller, more secure cloud zones. And then enforce strict access policies for each zone. This best practice will help you understand who accesses your cloud services. You’ll also know what they do with your data resources. Use role-based access control Role-based access control allows you to assign users different access rights based on their roles. This method lessens the chances of giving people unauthorized access privileges. It also simplifies the administration of access rights. RBAC also simplifies upholding the tenet of least privilege. It restricts user permission to only the resources they need to do their jobs. This way, users don’t have excessive access that attackers could exploit. Monitor suspicious activity Monitoring suspicious behavior involves tracking and analyzing user activity in a cloud environment. It helps identify odd activities, such as user accounts accessing unauthorized data. You should also set up alerts for suspicious activities. Adopting this security strategy will help you spot security incidents early and react quickly. This best practice will help you improve your cloud functionality. It will also protect your sensitive data from unwanted access or malicious activities. Monitor privileged users Privileged users have high-level access rights and permissions. They can create, delete and modify data in the cloud environment. You should consider these users as a huge cybersecurity risk. Your privileged users can cause significant harm if they get compromised. Closely watch these users’ access rights and activity. By doing so, you’ll easily spot misuse of permissions and avert data breaches. You can also use privileged access management systems (PAS) to control access to privileged accounts. Enforcing security certifications also helps privileged users avoid making grievous mistakes. They’ll learn the actions that can pose a cybersecurity threat to their organization. Best practices for protecting sensitive data Safeguarding sensitive data is critical for organizational security. You need security measures to secure the cloud data you store, process and transfer. Encrypt data in motion and at rest Encrypting cloud data in transit and at rest is critical to data security. When you encrypt your data, it transforms into an unreadable format. So only authorized users with a decryption key can make it readable again. This way, cybercriminals will not access your sensitive data. To protect your cloud data in transit, use encryption protocols like TSL and SSL. And for cloud data at rest, use powerful encryption algorithms like AES and RSA. Investigate shadow IT applications Shadow IT apps can present a security risk as they often lack the same level of security as sanctioned apps. Investigating Shadow IT apps helps ensure they do not pose any security risks. For example, some staff may use cloud storage services that are insecure. If you realize that, you can propose sanctioned cloud storage software as a service apps like Dropbox and Google Drive. You can also use software asset management tools to monitor the apps in your environment. A good example is the SaaS solution known as Flexera software asset management. Protect Endpoints Endpoints are essential in maintaining a secure cloud infrastructure. They can cause a huge security issue if you don’t monitor them closely. Computers and smartphones are often the weakest points in your security strategy. So, hackers target them the most because of their high vulnerability. Cybercriminals may then introduce ransomware into your cloud through these endpoints. To protect your endpoints, employ security solutions like antimalware and antivirus software. You could also use endpoint detection and response systems (EDRs) to protect your endpoints from threats. EDRs use firewalls as a barrier between the endpoints and the outside world. These firewalls will monitor and block suspicious traffic from accessing your endpoints in real time. Best practices for preventing social engineering attacks Use these best practices to protect your organization from social engineering attacks: Educate employees about threats Educating workers on the techniques that attackers use helps create a security-minded culture. Your employees will be able to detect malicious attempts and respond appropriately. You can train them on deception techniques such as phishing, baiting, and pretexting. Also, make it your policy that every employee takes security certifications on a regular basis. You can tell them to report anything they suspect to be a security threat to the IT department. They’ll be assured that your security team can handle any security issues they may face. Create and enforce a password policy A password policy helps ensure your employees’ passwords are secure and regularly updated. It also sets up rules everyone must follow when creating and using passwords. Some rules in your password policy can be: Setting a minimum password length when creating passwords. No reusing of passwords. The frequency with which to change passwords. The characteristics of a strong password. A strong password policy safeguards your cloud-based operations from social engineering assaults. Implement multi-factor authentication Multi-factor authentication adds an extra layer of security to protect the users’ accounts. This security tool requires users to provide extra credentials to access their accounts. For example, you may need a one-time code sent via text or an authentication app to log into your account. This extra layer of protection reduces the chances of unauthorized access to accounts. Hackers will find it hard to steal sensitive data even if they have your password. In the process, you’ll prevent data loss from your cloud platform. Leverage the multifactor authentication options that public cloud providers usually offer. For example, Amazon Web Services (AWS) offers multifactor authentication for its users. Best practices for securing your cloud deployments. Your cloud deployments are as secure or insecure as the processes you use to manage them. This is especially true for multi-cloud environments where the risks are even higher. Use these best practices to secure your cloud deployments: Understand the shared responsibility model The shared responsibility model is a concept that drives cloud best practices. It states that cloud providers and customers are responsible for different security aspects. Cloud service providers are responsible for the underlying infrastructure and its security. On the other hand, customers are responsible for their apps, data, and settings in the cloud. Familiarize yourself with the Amazon Web Services (AWS) or Microsoft Azure guides. This ensures you’re aware of the roles of your cloud service provider. Understanding the shared security model will help safeguard your cloud platform. Audit IaaS configurations Cloud deployments of workloads are prone to misconfigurations and vulnerabilities. So it’s important to regularly audit your Infrastructure as a Service (IaaS) configurations. Check that all IaaS configurations align with industry best practices and security standards. Regularly check for weaknesses, misconfigurations, and other security vulnerabilities. This best practice is critical if you are using a multi-cloud environment. The level of complexity arises, which in turn increases the risk of attacks. Auditing IaaS configurations will secure your valuable cloud data and assets from potential cyberattacks. Review SLAs and contracts. Reviewing SLAs and contracts is a crucial best practice for safeguarding cloud installations. It ensures that all parties know their respective security roles. You should review SLAs to ensure cloud deployments meet your needs while complying with industry standards. Examining the contracts also helps you identify potential risks, like data breaches. This way, you prepare elaborate incident responses. Best practices for incident response Cloud environments are dynamic and can quickly become vulnerable to cyberattacks. So your security/DevOps team should design incident response plans to resolve potential security incidents. Here are some of the best practices for incident response: Maintaining logs and monitoring Maintaining logs and monitoring helps you spot potential cybersecurity threats in real time. In the process, enable your security to respond quickly using the right security controls. Maintaining logs involves tracking all the activities that occur in a system. In your cloud environment, it can record login attempts, errors, and other network activity. Monitoring your network activity lets you easily spot a breach’s origin and damage severity. Use vulnerability and penetration testing Vulnerability assessment and penetration testing can help you identify weaknesses in your cloud. These tests mimic attacks on a company’s cloud infrastructure to find vulnerabilities that cybercriminals may exploit. Through automation, these security controls can assist in locating security flaws, incorrect setups, and other weaknesses early. You can then measure the adequacy of your security policies to address these flaws. This will let you know if your cloud security can withstand real-life incidents. Vulnerability and penetration testing is a crucial best practice for handling incidents in cloud security. It may dramatically improve your organization’s overall security posture. Consider intrusion detection and prevention Intrusion detection and prevention systems (IDPS) are essential to a robust security strategy. Intrusion detection involves identifying potential cybersecurity threats in your network. Through automation, intrusion detection tools monitor your network traffic in real-time for suspicious activity. Intrusion prevention systems (IPS) go further by actively blocking malicious activity. These security tools can help prevent any harm by malware attacks in your cloud environment. The bottom line on cloud security. You must enforce best practices to keep your cloud environment secure. This way, you’ll lower the risks of cyberattacks which can have catastrophic results. A CSPM tool like Prevasio can help you enforce your cloud security best practices in many ways. It can provide visibility into your cloud environment and help you identify misconfigurations. Prevasio can also allow you to set up automated security policies to apply across the entire cloud environment. This ensures your cloud users abide by all your best practices for cloud security.

Network Security 5 Best Network Vulnerability Scanning Tools in 2024 Tsippi Dach 2 min read Tsippi Dach Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 2/11/24 Published Network vulnerability scanning provides in-depth insight into your organization’s security posture and highlights the specific types of vulnerabilities attackers may exploit when targeting it. These tools work by systematically scanning your network environment — including all desktops, laptops, mobile endpoints, servers, and other assets for known weaknesses and misconfigurations. Your analyzer then produces a detailed report that tells you exactly how hackers might breach your systems. Find out how these important tools contribute to successfully managing your security policies and protecting sensitive assets from cybercriminals and malware. What is Network Vulnerability Management? Network vulnerability scanners are cybersecurity solutions typically delivered under a software-as-a-service (SaaS) model. These solutions match your network asset configurations with a comprehensive list of known misconfigurations and security threats, including unpatched software, open ports, and other security issues. By comparing system details against a comprehensive database of known vulnerabilities, network scanning helps pinpoint areas of weakness that could potentially be exploited by threat actors. This proactive approach is essential for maintaining robust network security and protecting sensitive data from unauthorized access and cyberattacks. This provides your organization with several valuable benefits: Early detection of known security vulnerabilities. If your organization is exposed to security threats that leverage known vulnerabilities, you’ll want to address these security gaps as soon as possible. Comprehensive data for efficient risk management. Knowing exactly how many security vulnerabilities your organization is exposed to gives you clear data for conducting in-depth risk management . Regulatory compliance. Many regulatory compliance frameworks like SOC 2, ISO 27001, and PCI DSS require organizations to undergo regular vulnerability scanning. Reduced costs. Automating the process of scanning for vulnerabilities reduces the costs associated with discovering and remediating security weaknesses manually. Key Features and Functions The best network security vulnerability scanners have several important features in common: Prioritized vulnerability assessment tools. You need to be able to assess and prioritize vulnerabilities based on their severity. This allows you to commit security resources to addressing high-priority vulnerabilities first, and taking care of low-impact weaknesses afterwards. Automation and real-time analysis. Manual scanning is a difficult and time-consuming process. Your vulnerability scanner must support automated, ongoing scanning for real-time vulnerability detection, providing on-demand insights into your security risk profile. Integration with remediation tools: The best network vulnerability scanners integrate with other security tools for quick mitigation and remediation. This lets security teams quickly close security gaps and move on to the next, without having to spend time accessing and managing a separate set of security tools. How Network Vulnerability Scanning Tools Work Step 1. Scanning Process Initial network mapping is the first step in the vulnerability scanning process. At this point, your scanner maps your entire network and identifies every device and asset connected to it. This includes all web servers, workstations, firewalls , and network devices. The automatic discovery process should produce a comprehensive map showing how your network is connected, and show detailed information about each network device. It should include comprehensive port scanning to identify open ports that attackers could use to gain entry to the network. Step 2. Detection Techniques The next step in the process involves leveraging advanced detection techniques to identify known vulnerabilities in the network. Most network vulnerability scanners rely on two specific techniques to achieve this: Signature-Based Detection: The scanner checks for known vulnerabilities by comparing system details against a database of known issues. This database is drawn from extensive threat intelligence feeds and public records like the MITRE CVE Program . Heuristic Analysis: This technique relies on heuristic and behavioral techniques to identify unknown or zero-day vulnerabilities based on unusual system behavior or configurations. It may detect suspicious activities that don’t correspond to known threats, prompting further investigation. Step 3. Vulnerability Identification This step involves checking network assets for known vulnerabilities according to their unique risk profile. This includes scanning for outdated software and operating system versions, and looking for misconfigurations in network devices and settings. Most network scanners achieve this by pinging network-accessible systems, sending them TCP/UDP packets, and remotely logging into compatible systems to gather detailed information about them. Highly advanced network vulnerability scanning tools have more comprehensive sets of features for identifying these vulnerabilities, because they recognize a wider, more up-to-date range of network devices. Step 4. Assessment and Reporting This step describes the process of matching network data to known vulnerabilities and prioritizing them based on their severity. Advanced network scanning devices may use automation and sophisticated scripting to produce a list of vulnerabilities and exposed network components. First, each vulnerability is assessed for its potential impact and risk level, often based on industry-wide compliance standards like NIST. Then the tool prioritizes each vulnerability based on its severity, ease of exploitation, and potential impact on the network. Afterwards, the tool generates a detailed report outlining every vulnerability assessed and ranking it according to its severity. These reports guide the security teams in addressing the identified issues. Step 5. Continuous Monitoring and Updates Scanning for vulnerabilities once is helpful, but it won’t help you achieve the long-term goal of keeping your network protected against new and emerging threats. To do that, you need to continuously monitor your network for new weaknesses and establish workflows for resolving security issues proactively. Many advanced scanners provide real-time monitoring, constantly scanning the network for new vulnerabilities as they emerge. Regular updates to the scanner’s vulnerability database ensure it can recognize the latest known vulnerabilities and threats. If your vulnerability scanner doesn’t support these two important features, you may need to invest additional time and effort into time-consuming manual operations that achieve the same results. Step 6. Integration with Other Security Measures Security leaders must pay close attention to what happens after a vulnerability scan detects an outdated software patch or misconfiguration. Alerting security teams to the danger represented by these weaknesses is only the first step towards actually resolving them, and many scanning tools offer comprehensive integrations for launching remediation actions. Remediation integrations are valuable because they allow security teams to quickly address vulnerabilities immediately upon discovering them. The alternative is creating a list of weaknesses and having the team manually go through them, which takes time and distracts from higher-impact security tasks. Another useful integration involves large-scale security posture analytics. If your vulnerability assessment includes analysis and management tools for addressing observable patterns in your network vulnerability scans, it will be much easier to dedicate resources to the appropriate security-enhancing initiatives. Choosing a Network Vulnerability Scanning Solution There are two major categories of features that network vulnerability scanning tools must offer in order to provide best-in-class coverage against sophisticated threats. Keep these aspects in mind when reviewing your options for deploying vulnerability scans in your security workflow. Important Considerations Comprehensive Vulnerability Database. Access to an extensive CVE database is vital. Many of these are open-source and available to the general public, but the sheer number of CVE records can drag down performance. The best vulnerability management tools have highly optimized APIs capable of processing these records quickly. Customizability and Templates. Tailoring scans to specific needs and environments is important for every organization, but it takes on special significance for organizations seeking to demonstrate regulatory compliance. That’s because the outcome of compliance assessments and audits will depend on the quality of data included in your reports. False Positive Management. All vulnerability scanners are susceptible to displaying false positives, but some manage these events better than others. This is especially important in misconfiguration cases, because it can cause security teams to mistakenly misconfigure security tools that were configured correctly in the first place. Business Essentials Support for Various Platforms. Your vulnerability scan must ingest data from multiple operating systems like Windows, Linux, and a variety of cloud platforms. If any of these systems are not compatible with the scanning process, you may end up with unstable performance or unreliable data. Reporting and Analytics. Detailed reports and analytics help you establish a clear security posture assessment. Your vulnerability management tool must provide clear reports that are easy for non-technical stakeholders to understand. This will help you make the case for necessary security investments in the future. Scalability and Flexibility. These solutions must scale with the growth of your organization’s IT infrastructure . Pay attention to the usage and payment model each vulnerability scanning vendor uses. Some of them may be better suited to small, growing organizations while others are more appropriate for large enterprises and government agencies. Top 5 Network Vulnerability Scanning Providers 1.

Tags Share this article 12/22/20 Published In the previous parts of our blog ( part I and part II ), we have described the most important parts of the Sunburst backdoor functionality and its Domain Generation Algorithm (DGA). This time, let’s have a deeper look into the passive DNS requests reported by Open-Source Context and Zetalytics . The valid DNS requests generated by the malware fall into 2 groups: DNS requests that encode a local domain name DNS requests that encode data The first type of DNS requests allows splitting long domain names into separate requests. These requests are generated by the malware’s functions GetPreviousString() and GetCurrentString() . In general, the format of a DNS request that encodes a domain name may look like: USER_ID.NUM.COMPUTER_DOMAIN[.]appsync-api.us-west-2[.]avsvmcloud[.]com where: USER_ID is an 8-byte user ID that uniquely identifies a compromised host, encoded as a 15-character string NUM is a number of a domain name – either 0 or 1, encoded as a character COMPUTER_DOMAIN is an encoded local computer domain Let’s try decoding the following 3 DNS requests: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com String 1 Let’s start from the 1st string in the list: olc62cocacn7u2q22v02eu.appsync-api.us-west-2.avsvmcloud.com. In this string, the first 15-character string is an encoded USER_ID : “olc62cocacn7u2q” . Once it is base-64 decoded, as explained in the previous post, it becomes a 9-byte byte array: 86 7f 2f be f9 fb a3 ae c4 The first byte in this byte array is a XOR key: 0x86 . Once applied to the 8 bytes that follow it, we get the 8-byte user ID – let’s take a note and write it down, we will need it later: f9 a9 38 7f 7d 25 28 42 Next, let’s take the NUM part of the encoded domain: it’s a character “2” located at the position #15 (starting from 0) of the encrypted domain. In order to decode the NUM number, we have to take the first character of the encrypted domain, take the reminder of its division by 36 , and subtract the NUM ‘s position in the string “0123456789abcdefghijklmnopqrstuvwxyz” : num = domain[0] % 36 – “0123456789abcdefghijklmnopqrstuvwxyz”.IndexOf(domain.Substring(15, 1)); The result is 1 . That means the decrypted domain will be the 2nd part of a full domain name. The first part must have its NUM decoded as 0. The COMPUTER_DOMAIN part of the encrypted domain is “2v02eu” . Once decoded, using the previously explained method, the decoded computer domain name becomes “on.ca” . String 2 Let’s decode the second passive DNS request from our list: r1qshoj05ji05ac6eoip02jovt6i2v0c.appsync-api.us-west-2.avsvmcloud.com Just as before, the decoded 8-byte user ID becomes: f9 a9 38 7f 7d 25 28 42 The NUM part of the encoded domain, located at the position #15 (starting from 0), is a character “6” . Let’s decode it, by taking the first character ( “r” = 114 ), take the reminder of its division by 36 ( 114 % 36 = 6 ), and subtracting the position of the character “6” in the “0123456789abcdefghijklmnopqrstuvwxyz” , which is 6 . The result is 0 . That means the decrypted domain will be the 1st part of the full domain name. The COMPUTER_DOMAIN part of the encrypted domain is “eoip02jovt6i2v0c” . Once decoded, it becomes “city.kingston.” Next, we need to match 2 decrypted domains by the user ID, which is f9 a9 38 7f 7d 25 28 42 in both cases, and concatenate the first and the second parts of the domain. The result will be “city.kingston.on.ca” . String 3 Here comes the most interesting part. Lets try to decrypt the string #3 from our list of passive DNS requests: lt5ai41qh5d53qoti3mkmc0.appsync-api.us-west-2.avsvmcloud.com The decoded user ID is not relevant, as the decoded NUM part is a number -29 . It’s neither 0 nor 1 , so what kind of domain name that is? If we ignore the NUM part and decode the domain name, using the old method, we will get “thx8xb” , which does not look like a valid domain name. Cases like that are not the noise, and are not some artificially encrypted artifacts that showed up among the DNS requests. This is a different type of DNS requests. Instead of encoding local domain names, these types of requests contain data. They are generated by the malware’s function GetNextStringEx() . The encryption method is different as well. Let’s decrypt this request. First, we can decode the encrypted domain, using the same base-64 method, as before . The string will be decoded into 14 bytes: 7c a5 4d 64 9b 21 c1 74 a6 59 e4 5c 7c 7f Let’s decode these bytes, starting from the 2nd byte, and using the first byte as a XOR key. We will get: 7c d9 31 18 e7 5d bd 08 da 25 98 20 00 03 In this array, the bytes marked in yellow are an 8-byte User ID, encoded with a XOR key that is selected from 2 bytes marked in red. Let’s decode User ID: for ( int i = 0 ; i < 8 ; i++) { bytes[i + 1 ] ^= bytes[ 11 - i % 2 ]; } The decoded byte array becomes: 7c f9 a9 38 7f 7d 25 28 42 25 98 20 00 03 The User ID part in marked in yellow. Does it look familiar? Indeed, it’s the same User ID we’ve seen before, when we decoded “city.kingston.on.ca” . The next 3 bytes marked in red are: 25 98 20 . 2 0x59820 The first number 2 stands for the size of data that follows – this data is 00 03 (selected in green). The number 0x59820 , or 366,624 in decimal, is a timestamp. It’s a number of 4-second periods of time since 1 January 2010. To obtain the real time stamp, we need to multiple it by 15 to get minutes, then add those minutes to 1 January 2010: var date = ( new DateTime( 2010 , 1 , 1 , 0 , 0 , 0 , DateTimeKind.Utc)).AddMinutes(timestamp * 15 ); For the number 0x59820 , the time stamp becomes 16 July 2020 12:00:00 AM – that’s the day when the DNS request was made. The remaining 2 bytes, 00 03 , encrypt the state of 8 security products, to indicate whether each one of them is running or whether it is stopped. The 8 security products are: Windows Live OneCare / Windows Defender Windows Defender Advanced Threat Protection Microsoft Defender for Identity Carbon Black CrowdStrike FireEye ESET F-Secure 2 states for 8 products require 2 * 8 = 16 bits = 2 bytes. The 2 bytes 00 03 in binary form are: 00 00 00 00 00 00 00 11 Here, the least-significant bits 11 identify that the first product in the list, Windows Live OneCare / Windows Defender, is reported as ‘running’ ( 1 ) and as ‘stopped’ ( 1 ). Now we know that apart from the local domain, the trojanised SolarWinds software running on the same compromised host on “city.kingston.on.ca” domain has also reported the status of the Windows Defender software. What Does it Mean? As explained in the first part of our description, the malware is capable of stopping the services of security products, be manipulating registry service keys under Administrator account. It’s likely that the attackers are using DNS queries as a C2 channel to first understand what security products are present. Next, the same channel is used to instruct the malware to stop/deactivate these services, before the 2nd stage payload, TearDrop Backdoor, is deployed. Armed with this knowledge, let’s decode other passive DNS requests, printing the cases when the compromised host reports a running security software. NOTES: As a private case, if the data size field is 0 or 1 , the timestamp field is not followed with any data. Such type of DNS request is generated by the malware’s function GetNextString() . It is called ‘a ping’ in the listing below. If the first part of the domain name is missing, the recovered domain name is pre-pended with ‘*’ . The malware takes the time difference in minutes, then divides it by 30 and then converts the result from double type to int type; as a result of such conversion, the time stamps are truncated to the earliest half hour. 2D82B037C060515C SFBALLET Data: Windows Live OneCare / Windows Defender [running] 11/07/2020 12:00:00 AM Pings: 12/07/2020 12:30:00 AM 70DEE5C062CFEE53 ccscurriculum.c Data: ESET [running] 17/04/2020 4:00:00 PM Pings: 20/04/2020 5:00:00 PM AB902A323B541775 mountsinai.hospital Pings: 4/07/2020 12:30:00 AM 9ACC3A3067DC7FD5 *ripta.com Data: ESET [running] 12/09/2020 6:30:00 AM Pings: 13/09/2020 7:30:00 AM 14/09/2020 9:00:00 AM CB34C4EBCB12AF88 DPCITY.I7a Data: ESET [running] 26/06/2020 5:00:00 PM Pings: 27/06/2020 6:30:00 PM 28/06/2020 7:30:00 PM 29/06/2020 8:30:00 PM 29/06/2020 8:30:00 PM E5FAFE265E86088E *scroot.com Data: CrowdStrike [running] 25/07/2020 2:00:00 PM Pings: 26/07/2020 2:30:00 PM 26/07/2020 2:30:00 PM 27/07/2020 3:00:00 PM 27/07/2020 3:00:00 PM 426030B2ED480DED *kcpl.com Data: Windows Live OneCare / Windows Defender [running] 8/07/2020 12:00:00 AM Carbon Black [running] 8/07/2020 12:00:00 AM Full list of decoded pDNS requests can be found here .

Security Policy Management with Professor Wool Best Practices: Incorporating Security into DevOps Best Practices for Incorporating Security into DevOps, is a whiteboard-style series of lessons that examine the challenges of and provide technical tips for how to incorporate security throughout the DevOps process. Lesson 1 In this lesson, Professor Wool examines the need for and the process of adjusting application connectivity throughout each stage of the DevOps lifecycle. Best Practices for Incorporating Security Automation into the DevOps Lifecycle Watch Lesson 2 In theory adding capacity should be fairly straightforward, with minimal need for any intervention by the organization’s security team. But in practice it’s a little more complex. In this video Professor Wool provides some tips and best practices to help you add capacity without having to change your security policies, complete a security review or worse still, cause an outage or gap in the security perimeter. Tips for Adding Capacity Without Changing Your Security Policies Watch Lesson 3 In a typical DevOps scenario development team adds new functionality to an existing business application and then rolls it out into production. However, while the new functionality worked as planned in both the test and pre-production environments, the application then fails when moved into the live production environment. In this video, Professor Wool will discuss the reasons why this process went wrong, and how you can fix it. How to Integrate Security into the Test Environment Watch Lesson 4 In previous lessons Professor Wool discussed how building security into DevOps processes at an early stage helps organizations maximize the speed and agility of application development, while minimizing the risks of problems and outages when the applications go live. In this whiteboard video Professor Wool looks at how security automation helps to speed up the practice of Continuous Integration (CI) - a core element of DevOps.

success stories "Today, we are many times more efficient and secure thanks to AlgoSec." Background The company’s globally distributed network includes more than ten demilitarized zones (DMZs) with 20 billion events processed per month across the multiple company locations. Firewalls play a vital role in protecting intellectual property at the perimeter level. Every firewall event is logged and processed. Challenges The company’s operations require a very large and diverse network with a large Global Network Security operations team that is spread across the US, EMEA and Asia. The team is responsible for the management of all perimeter and internal security solutions, remote access solutions, customer connectivity solutions and the Security Operations Center (SOC). “We suffered from a lot of network security issues that prevented us from running at the speed of the business,” declared the Senior Manager of Global Security and SOC. Auditing Firewall rules was a long, tedious and painful process Access revocation was performed using a manual reminders process The diverse army of firewalls across the network estate resulted in a non-standard way of making and executing Firewall change requests, requiring many steps to complete the process An out-of-the-box ServiceNow workflow with limited functionality couldn’t keep up Limited reporting capabilities relied on manual data processing There was no way to track performance of SLAs The cumbersome approval process required managers to login to the company ticketing portal Notification of unauthorized or unapproved changes on firewalls was clumsy and slow The company decided to acquire an orchestration and automation solution that could identify and mitigate risky firewall rules. Since the company is subject to many industry and legal regulations, the solution would have to automate compliance reporting as well as ensure accountability for all firewall changes. The solution also would have to integrate into existing ticketing processes and workflows while enabling the company, at its own pace, to advance to more and more automation. Solution The company evaluated several solutions by reviewing their features carefully and putting the best among them to the test in parallel proof of concept projects. The senior manager recalls, “We had a very close look at the leading solutions in the Network Security Policy Management space. One of them definitely stood out from the pack as the superior solution.” The company chose AlgoSec Firewall Analyzer (AFA) and AlgoSec FireFlow (AFF), two of the flagship products in the AlgoSec arsenal. AlgoSec Firewall Analyzer ensures security and compliance by providing visibility and analysis into complex network security policies. AlgoSec FireFlow improves security and saves security staffs’ time by automating the entire security policy change process, eliminating manual errors, and reducing risk. Results In short order, the company was able to capitalize on the significant advantages of the AlgoSec solution. “It was easy to customize the AlgoSec solution to fit into our environment and enhance it,” continued the senior manager. “But it didn’t take long before we were using the power of the two products to help us adopt better practices for lower risk, higher security, and better efficiency of our team.” Today, the AlgoSec solution is delivering significant improvements to the company’s security processes such as: Visibility across the entire network with an easy-to-use-and-understand executive dashboard Integration with the ticketing tool Proactive analysis of change requests to ensure compliance risk mitigation Prevention of unauthorized changes Elimination of human errors and associated application outages Automatic discovery and mapping of application-connectivity flows Single Sign On (SSO) integration that eliminated static user passwords Support for mobile firewall change-request manager approval “We are a big company with an enormous volume of network-security activity,” stated the manager. “In addition to the superior capabilities of the solution, we greatly appreciated the excellent customization opportunities that AlgoSec’s Professional Services were able to help us with. Today, we are many times more efficient and secure thanks to AlgoSec.” Schedule time with one of our experts
